PESTICIDE FORMULATION: Emulsifiable Concentrates (EC) & Our Emulsifier Portfolio
The Emulsifiable Concentrate (EC) remains one of the most common and trusted formulation types for crop protection products worldwide.
An EC is a homogeneous, transparent oil-based liquid, prepared by dissolving the technical active ingredient into an organic solvent, combined with a precise ratio of specialized emulsifiers. Upon dilution with water, it spontaneously forms a highly stable emulsion—ensuring uniform spray coverage and consistent field application.
Key Advantages of EC:
- Simplified formulation & mature technology – easy to manufacture
- Excellent storage stability & high-loading capability
- Easy processing & high field efficacy
Essential Quality Standards of EC:
- Clear appearance
- Spontaneous emulsification
- Long-term emulsion stability
Future Trend:
The industry is moving toward greener, safer, and high-flash-point solvent systems to reduce environmental impact while maintaining performance.
Main Components:
a.i. + emulsifiers + solvent
The emulsifier system is the critical component that determines the quality and performance of an EC formulation. Upon dilution with water, emulsifiers ensure that the active ingredient and solvent are uniformly dispersed, creating a stable emulsion that meets the requirements for even spray coverage and consistent field application.
Our Comprehensive Emulsifier Portfolio:
Anionic Emulsifiers
- Calcium Dodecylbenzene Sulfonate (linear & branched, isobutanol & 2-ethylhexanol)
Commonly used alongside non-ionic partners.
Non-Ionic Emulsifiers
- Tristyrylphenol Ethoxylates
- Castor Oil Ethoxylates
- Fatty Alcohol Ethoxylates (primary alcohol, secondary alcohol, isotridecyl alcohol, isodecyl alcohol)
- Tween & Span
From EC fundamentals to the emulsifiers that make them work—we've got your formulation covered.
